Viagra should be taken on demand about half an hour or an hour before the planned sexual intercourse. The tablet should be washed down with water. To maximize the effect of the drug, it is advisable to take it on an empty stomach or after a light meal, avoiding large and fatty foods, which slow down the absorption of Viagra into the blood and can weaken its effect on the male body. Viagra can be taken no more than once a day, regardless of what dosage you use. Avoid taking Viagra in combination with alcohol, unless it is a small amount of a weak alcoholic drink, with narcotic substances and other drugs to increase potency, including other PDE-5 inhibitors.
The optimal time for taking Viagra before sexual intercourse is from 30 to 60 minutes. It is difficult to give more precise recommendations, because each man reacts to taking this medicine individually, depending on many parameters, such as individual sensitivity to sildenafil citation, the active substance of Viagra, body weight, the rate of absorption of the drug into the blood depending on the fullness of the stomach, the degree of erectile dysfunction. However, the general fact is that the effect of taking Viagra very rarely begins to manifest earlier than half an hour after taking this medicine. There is no point in taking Viagra and strong in advance, for example, two or three hours before the planned sex, because in this case the duration of the drug’s action will be shorter.
The most active action of Viagra usually lasts about two or three hours. After this time, the drug’s effect on erection begins to wane, but it can be felt for up to five or six hours, depending on the dosage, the individual man’s metabolic characteristics, and other factors such as the severity of erectile dysfunction, the patient’s body weight, age, and individual sensitivity to Viagra.
Viagra helps relieve symptoms of erectile dysfunction by strengthening and prolonging an erection. This is possible because the drug helps increase blood flow to the cavernous bodies of the penis when a man is sexually aroused or sexually stimulated. When a man takes Viagra and experiences sexual desire or sexual stimulation, his body responds with a stronger and longer erection by inhibiting the production of the enzyme PDE-5, a substance that is secreted in the cavernous bodies of the penis and is responsible for stopping an erection. Viagra also dilates the blood vessels in the penis by increasing the production of nitric oxide and the compound cGMP, which helps relax the smooth muscles of the arterial wall of the penis. However, Viagra does not affect a man’s libido or his hormonal levels.
As a rule, it is not recommended to drink alcohol for half an hour before taking Viagra and at least two hours after, because alcohol can significantly increase the side effects of Viagra, leading to a strong decrease in blood pressure and severe dizziness. In patients with hypertension, blood pressure, on the contrary, rises. In addition, alcohol increases the load that Viagra has on the cardiovascular system, which can lead to significant harm to the heart. Most cases of sudden cardiac death associated with taking Viagra were associated with a combination of this drug with large amounts of alcohol and drugs. Therefore, if you want to ensure your safety when taking Viagra, avoid drinking alcohol for at least two to three hours after taking this drug.
After taking Viagra, it remains in the patient’s body for quite a long time, up to six hours. However, the most pronounced effect of this drug lasts from two to three hours. This time is more than enough for both partners to be fully satisfied with sex, even if the man has a strong sexual constitution and is able to perform two or three sexual acts. As for the duration of Viagra’s action within any course of treatment or long-term use of this drug, it has no restrictions on the duration of use. This is due to the fact that taking Viagra does not lead to the development of physical or psychological dependence.
Viagra is not approved for use by people under 18 years of age. However, it should be noted that some people purchase Viagra and its sildenafil-based analogues, including for younger people, but only when these drugs are used to treat pulmonary arterial hypertension. In the case of use by minors, naturally, no one can talk about treating erectile dysfunction.
Viagra affects the male sexual system only if there is sexual arousal or sexual stimulation. Thus, if a man takes Viagra and for some reason sex does not occur, he will not suffer from an erection or a feeling of sexual desire that occurs against his will, since this drug does not affect sex hormones. However, even if after taking Viagra a sexual situation does not occur and arousal does not occur, the drug still affects the body. Therefore, a man may experience side effects – exactly the same as he would experience if he had sex.
Cialis and Viagra are drugs from the same pharmacological group of PDE-5 inhibitors. Cialis differs in that it remains in the man’s body for a long time, up to one and a half days. Therefore, in order to avoid the effect of one drug overlapping the effect of another and to avoid the development of serious side effects, you can take Viagra after taking Cialis only if at least 36 hours have passed since the last time you took Cialis. It is optimal to wait two days so that no traces of the active substance of Cialis – Tadalafil – remain in the body. Otherwise, clinically significant side effects and symptoms of overdose and intoxication may be observed.
The most common side effects of Viagra are headache and a feeling of blood rushing to the skin of the face. As a rule, side effects are mild or moderate and are transient. The frequency of some adverse events increases with increasing dose.
As for the organs of vision, patients often note blurred vision and impaired color perception, mainly the coloring of objects in bluish or greenish tones. Photophobia, redness of the eyes, a feeling of dryness may also be observed. Other side effects associated with vision are quite rare. A common side effect of taking Viagra is dizziness, noise or ringing in the ears. Patients may note a feeling of palpitations, tachycardia, a decrease or increase in blood pressure. Men with cardiovascular diseases may experience quite severe side effects, such as unstable angina, a feeling of palpitations, cerebral thrombosis, heart failure, abnormalities in ECG readings. In terms of metabolism, the drug may cause a feeling of thirst and swelling.
Viagra’s ability to dilate blood vessels causes such a common side effect as nasal congestion. In terms of the digestive system, nausea, dyspepsia, hemorrhoids, bloating, abdominal pain, exacerbation of gastritis and gastric ulcer or duodenal ulcer may be observed. In terms of the musculoskeletal system, some patients experience pain in the back and limbs. Taking Viagra is also fraught with neuralgia, insomnia or unusual dreams. Fainting may rarely occur. Fever, flu-like syndrome, development of infectious diseases are possible; uncommon – facial edema, shock, asthenia, increased fatigue, chills, accidental falls, chest pain.
Today, it is possible to buy both branded Viagra and its generics without a doctor’s prescription, using the services of primarily online pharmacies, legally based in countries where the requirements for the prescription status of the drug are formal and patients are not asked to confirm that they have a current prescription. First of all, India is one of these countries. Therefore, many men buy Viagra without a prescription, contacting Indian national online pharmacies, as well as large international pharmacies that sell Indian drugs. It is important to remember that before buying Viagra over the counter, you need to carefully study the instructions and be sufficiently informed about your health.
